With the deep integration of information technology and education, online reflection by teachers has become a crucial pathway for promoting their professional development. The study, based on a longitudinal case study, explores the characteristics of teaching reflection and social interaction in an online community of teachers, as well as their impact on teacher professional development. Through stratified sampling of community message data from 2014 to 2021, and utilizing content analysis and soc ial network analysis, the dynamic features of online reflection activities among teachers were explored in depth. The study found that teachers' online reflection exhibits regular daily and annual patterns, with a primary focus on classroom teaching and individual teacher development. Additionally, technical reflection and interpretive reflection were more prevalent than critical reflection. Social network analysis revealed that social interactions among teachers provide the trust foundation and group dynamics necessary for reflective activities, while teaching reflection offers metacognitive strategies that support social interactions , the two processes reinforce each other. Furthermore, the study showed that teachers' social interactions directly impacted the community's knowledge construction and sharing, playing a crucial role in maintaining the community's sustainable development. Further analysis revealed that by engaging in multi-level and multi-dimensional online reflection and social interaction, teachers were more likely to apply reflective outcomes to teaching practice, thereby creating new opportunities for professional development. This study provides valuable insights into how teachers can leverage online reflection to enhance their professional growth. |
